Abstract: A preferred embodiment of the invention comprises a tool chuck (10) for a power hand tool (14) of the type which has a generally cylindrical elongated housing with a motor contained within the housing or case and the motor having an output shaft (12) that extends from the nose end of the hand tool (14), and which has one or more light producing devices (24) located at its nose end for illuminating the work area during operation. The preferred embodiment of the tool chuck (10) has an annular cylindrical light transmitting portion (44) on the outside of the chuck body portion (30) for transmitting light toward a tool bit (20) held by the tool chuck (10). The preferred embodiment may have an inwardly oriented front end surface (46) to direct the transmitted light toward the axis of the tool bit and may have an outer layer of resilient material (48) to facilitate easy gripping of the tool chuck (10) to tighten or loosen a tool bit.
